EGL. Known in Victoria by a single 1905 collection at NSW herbarrium and labelled 'Orbost'. The habitat in Victoria is unknown, but in New South Wales the species occurs in lowland swampy vegetation.

Probably extinct in Victoria. The solitary record for this state is some 350 km remote from the nearest known occurrence near Ulladulla, New South Wales. It is rare throughout its range (to as far north as Sydney).
